As some one who works with children on a daily basis, one can see how mean children can be towards each other.
Say a child is overweight or is new to this country and does not speak the language very well. He or she is bullied the entire day at school and on the bus. They are told if they say anything to school officials or to their parents, the bullying will become worse.
These kids need to be taught it's not ok to bully anyone. Just treat each other with respect. Thank goodness will help mitigate this bullying situation.
